Performance Parameters and Context of Use
2001The acceptance of software is determined in how far users can be satisfied in the context of using the software. In this chapter context of use is defined in terms of usability-engineering parameters. A first step towards conceptual integration of software-performance engineering with usability engineering is described. Performance engineering in terms

Time locality: A novel parameter for quality of context
2010 Seventh International Conference on Networked Sensing Systems (INSS), 2010Context awareness is a key technology in pervasive computing. Quality of context (QoC) is a compound measurement to rate the potential correctness of a context value. The different physical sensors aggregated to infer a context, naturally have different update frequencies. However the only time related QoC parameter is “up-to-dateness”, which refers to

Granularity as a Parameter of Context
2005Spatial and temporal granularity can be understood as parameters of context restricting the set of accessible objects in a context. Starting from the idea that this selection process depends to a large extent on the relation between the grain-size of the context and the local extension of the objects, the granularity of a context is in this article ...

Context-correlated parameters of snake and lizard tongue-flicking
Animal Behaviour, 1983Abstract Three parameters of tongue-flicking in snakes and lizards (oscillation duration, oscillation number and relative circumscribed area) were examined in filmed captive contexts. A comparative survey of four lizard and 10 snake species uncovered a consistent trend for exploratory tongue flicks to have both shorter oscillation durations and ...

Novel Blind Interleaver Parameter Estimation in a Noncooperative Context
IEEE Transactions on Aerospace and Electronic Systems, 2019It is well known that the distribution of the ranks of random matrices follows a specific distribution. By partitioning ranks into two possible outcomes, we can transform the estimating interleaver parameters into the counting of success events. Using this probabilistic framework, we can efficiently determine interleaver parameters in a noncooperative ...

Business-Context Based SLA Parameters for SOA Management
2011With Web services starting to be deployed within organizations and being offered as paid services across organizational boundaries, quality of service (QoS) has become one of the key issues to be addressed by providers and clients. While methods to describe and advertise QoS properties have been developed, the main outstanding issue remains how to ...

Context Parameter Prediction to Prolong Mobile Terminal Battery Life
2012Energy is a critical resource for mobile devices, which depend on batteries for power supply. With the high energy requirements of the new wireless generation, there is a definite need for new techniques for power saving. The C2POWER project is an European project having the goal of implementing energy-saving techniques for multi-standard Mobile ...

Adaptive Measurement of Change in the Context of Item Parameter Drift
Applied Psychological MeasurementAdaptive measurement of change (AMC) uses computerized adaptive testing (CAT) to measure and test the significance of intraindividual change on one or more latent traits. The extant AMC research has so far assumed that item parameter values are constant across testing occasions.
